"it becomes cooler than the surrounding air by around 9F (5C)"
Sorry, not possible, as per the first law of thermodynamics.
How in the hell do you think dew gets deposited on grass, cars, etc? Dew forms when the surface temperature drops below the dew point of the air, which cannot be any higher than the ambient air temperature.
FWIW, a problem from my engineering heat transfer course indicated that frost can form when the air temp is 9F/5C above freezing.
And fiber has even more bandwidth than copper.
Your point is correct about fixed links providing far more bandwidth that what can be provided by any kind of wireless link. The drone concept only make sense in places like the lightly populated areas of the US or similar countries where customers are too far apart to make wireline or fiber communications affordable. The low altitude with respect to satellites means that the link frequencies can be re-used more frequently.
Actually, you're the one who comes across as being ignorant.
Baseload generation is generation is considered to be the lowest incremental cost dispatchable power source. No form of generation has 100% up time, but a well run plant will have very little unscheduled down time. The variability of wind is a huge problem when wind generation becomes a significant portion of total generation at a give moment, requiring a large amount of spinning reserve to keep the grid stable.
FWIW, the limiting factor in power output of an AC generator is not conductor heating, rather it is the amount of power that can be generated without the generator pulling out of synchronism, especially under fault conditions.
While this book is not a Tesla biography, it does give a good picture of how Tesla fit in with the beginnings of the electric power industry. The book does give Tesla proper credit for the invention of poly-phase AC and the induction motor, but also points out that Stanley and Thomson were working on AC distribution before Tesla along with a lot of refinement on the induction motor being done by Benjamin Lamme.
It is the likes of Lamme and Steinmetz that are the unsung heroes of the electrical age.
Hmmm, "Get them out by Friday".
A bit OT, but I was surprised to learn that "Attack of the Giant Hogweed" was mostly based on fact.
